Is it necessary to posit separate, explicit distinctions between representations in order to account for dissociations between consonant and vowel processing? We argue that a cognitive model of speech production based on cumulative lower-level properties is not only sufficient but more parsimonious in accounting for aphasic and dysgraphic patient…

Examined are issues in the controversy over the existence of minimal cerbral dysfunction as a cause of cognitive and behavioral difficulties. (DB)

Many children wrongly diagnosed as emotionally disturbed, actually have a faulty sense of perception, known as minimal cerebral disfunction. This article describes some typical symptoms, and discusses ways such children might be helped. (MG)

A number of studies have been done on the relation between reading disability and complications of pregnancy and birth. The procedures and results of major studies are critically reviewed in this document, with attention given to issues of research design, test use, and statistical methods. Although none of the studies reviewed is free of…

Neurological impairment as discussed includes a range of disabilities referred to as neurological impairment: minimal brain dysfunction/damage, developmental disability, perceptual handicap, learning disability, hyperkinetic behavioral syndrome, and others. Defined are causes of neurological impairment and methods of diagnosis. Symptoms…

Focuses on how learning works. Discusses three major components related to processing information--sensory and perceptual systems, integration of information, and output of information--and developmental and environmental factors affecting brain information in each of these areas. Concludes with discussion of biological bases for cognitive and…

Examined with over 28,000 7-year-old children whose mothers registered for prenatal care was the relationship between perinatal complications and such characteristics as poor school achievement, hyperactivity, and neurological soft signs associated with the diagnosis of minimal brain dysfunction (MBD). Ten perinatal antecedents were studied:…

Minimal brain dysfunction (MBD) refers to a significant disturbance in several areas of a child's functioning. This condition includes learning disability, lack of motor coordination , auditory and/or visual perceptual disturbances, hyperactivity, and problems in concentration and attention span. Also involved is a heavy overlay of personality and…

Results of an experiment in which two speech sounds were presented simultaneously to the two ears in normal and unilaterally brain-damaged subjects suggest a role for the nondominant cerebral hemisphere in processing and/or storage of competing speech stimuli. (KW)

Summarized are three articles concerned with research on neurological aspects of learning disabilities entitled "Anomia-A Case of Pathological Verbal Dominance;""Brain--Right Hemisphere--Man's So Called 'Minor Hemisphere;""Neurology-A Special Neurological Examination of Children with Learning Disabilities". (DB)

Discusses the problems of helping a group of children that seem otherwise normal but cannot learn. (RB)

Differing viewpoints in the field have resulted in considerabe lack of agreement in definitions of learning disabilities. Considers problems and limitations resulting from these disagreements. (RB)
